Joshua Haberman	c69dd68fb1	Implement feature inheritance and legacy editions for upb. This switches upb to using legacy editions for all proto2/proto3 logic. This does not yet enable code generation for editions protos (ie. we do not yet turn on `FEATURE_SUPPORTS_EDITIONS`), but with feature inheritance in place, this will be a much smaller follow-on change. There is a ~10% increase in allocations, but only a ~1% increase in peak memory. There are some <5% increases in instructions and cycles, but apparently no increase in time: ``` name old cpu/op new cpu/op delta BM_ArenaOneAlloc 17.8ns ±11% 16.9ns ±17% ~ (p=0.310 n=5+5)

about 5Ki of code size. Some of this likely comes from the fact that we now link in `message/copy.c` to perform a deep copy of a FeatureSet proto. ``` $ /google/bin/releases/protobuf-team/bloaty/bloaty-google3-diff --blaze-build-opts="-c opt" third_party/upb/upb/conformance/conformance_upb FILE SIZE VM SIZE -------------- -------------- +0.5% +4.19Ki +0.5% +4.19Ki .text +0.4% +656 +0.4% +656 .rodata +0.1% +504 [ = ] 0 .strtab +0.2% +384 [ = ] 0 .symtab +0.2% +280 +0.2% +280 .eh_frame +0.2% +216 +0.2% +216 .rela.dyn +0.3% +96 +0.3% +96 .data.rel.ro +0.2% +64 +0.2% +64 .eh_frame_hdr +1.1% +16 [ = ] 0 .got.plt +0.2% +8 +0.2% +8 .rela.plt -4.6% -8 -4.6% -8 [LOAD #2 [RX]] -50.0% -48 [ = ] 0 [Unmapped] [ = ] 0 -81.7% -1.47Ki .relro_padding +0.1% +6.30Ki +0.0% +4.00Ki TOTAL ``` PiperOrigin-RevId: 579321454	1 year ago
Adam Cozzette	501ececd39	Reorganize upb file structure This change moves almost everything in the `upb/` directory up one level, so that for example `upb/upb/generated_code_support.h` becomes just `upb/generated_code_support.h`. The only exceptions I made to this were that I left `upb/cmake` and `upb/BUILD` where they are, mostly because that avoids conflict with other files and the current locations seem reasonable for now. The `python/` directory is a little bit of a challenge because we had to merge the existing directory there with `upb/python/`. I made `upb/python/BUILD` into the BUILD file for the merged directory, and it effectively loads the contents of the other BUILD file via `python/build_targets.bzl`, but I plan to clean this up soon.

Adam Cozzette	7286ffceb2	Merge the protobuf and upb Bazel repos A couple weeks ago we moved upb into the protobuf Git repo, and this change continues the merger of the two repos by making them into a single Bazel repo. This was mostly a matter of deleting upb's WORKSPACE file and fixing up a bunch of references to reflect the new structure. Most of the changes are pretty mechanical, but one thing that needed more invasive changes was the Python script for generating CMakeLists.txt, make_cmakelists.py. The WORKSPACE file it relied on no longer exists with this change, so I updated it to hardcode the information it needed from that file. PiperOrigin-RevId: 564810016	1 year ago
Adam Cozzette	047df98dea	Move upb-x/ back to upb/ This is the second attempt to fix our Git history. This should allow "git blame" to work correctly in the upb/ directory even though our automation unexpectedly blew away that directory.	1 year ago

Protobuf Team Bot	34585e9d2f	Clean up of rust messagegenerator and accessor generators. It ended up being odd to construct the AccessorGenerators ahead of time given some specific Context<>: since each of the three methods on AccessorGenerators demands a different Context than the initial one so they shouldn't hold that Context anyway. It ended up just being a spooky parallel array to the Fields with an unenforced invariant that all methods would be called with a new Context<> but the same underlying FieldDescriptor later.

Hong Shin	87e6b7f6e9	Sketch of v0.6 SingularMessageField This CL sets up the basic plumbing end-to-end for singular message fields. We add skeletonized support for `Proxied` messages. This is done by creating structs for $Msg$View and $Msg$Mut, and providing stubbed impls. PiperOrigin-RevId: 552609955	1 year ago

Miguel Young de la Sota	6678619d10	Factor out different codegen parts of the Rust backend. The intent of this change is to take the best ideas from the C++ backend, such as having generator objects that can cache pre-computed state, while minimizing duplication. Where possible, we take the approach of making the C++ and UPB kernel-specific code as similar as possible, since this reduces the number of templates we need to keep in sync.
